What are the rules for helmet decals?
For example, in VC15AP18's layout above, could the Jets switch and use a black NY/Jets logo sticker to just match that black jersey, or can decals only be swapped for color rush jerseys?
This doesn't mean I want to see the Jets do this, but I'm expecting the worst.

Black on green looks horrible. Black outlining white on green is unnecessary. Black outlined with white on green is not a good look.
Thanks Jets, for all the years of mediocrity and embarrassment you've put on the field, at least your uniforms will match.

Black is still unnecessary to the Jets in 1000 ways.
Yes, I know the 80s uniforms used black in the 90s, but it was strictly as an outline. Nobody calls out the Cowboys for using black outlines, so the idea of the Jets use of black is okay because they used it in the 90s is ridiculous.
The Jets are green and white. The Eagles are green, white and silver. Neither team needs black.
Boring, black jerseys or jingoism fighter pilot BS isn't needed to make the Jets identity look good or better.
I'm so scared this is so unnecessary when an easy fix (color, shoulder stripes) was all they needed.

It's easy to sum it up when you're just talking about primer. We're sitting in here, and I'm supposed to be talking the franchise, and we in here talking about primer. I mean, listen, we're talking about primer, not the goods, not the goods, not the goods, we talking about primer. Not the goods. Not, not … Not the goods that I go out there and die for. Not the goods, but we're talking about primer, man. I mean, how silly is that? … And we talking about primer. I know I supposed to be there. I know I'm supposed to lead by example... I know that... And I'm not.. I'm not shoving it aside, you know, like it don't mean anything. I know it's important, I do. I honestly do... But we're talking about primer man. What are we talking about? Primer? We're talking about primer, man. [laughter from the media crowd] We're talking about primer. We're talking about primer. We ain't talking about the goods. [more laughter] We're talking about primer, man. When you come to the arena, and you see them play, you see them play don't you? You've seen the, give everything they've got, right? But we're talking about primer right now. We talking about pr... [Interrupted].
Reporter: But it's an issue that the boards continues to raise?
Man look, I hear you... it's funny to me too, I mean it's strange... it's strange to me too, but we're talking about primer man, we're not even talking about the goods... the actual goods, when it matters... We're talking about primer …

Well, this would be effective if soccer teams could make jersey manufacturers use the patterns in their shirts every year, but the designed change so much it'll be there once and gone again real fast. This is an annoying thing about soccer and MLS in general - no team ever sticks to a pattern or design. It seems like all the patterns just get shifted around from team to team over the years. There's no Yankee pinstripes and there won't be any Nashville zubaz.

I don't mind it, but it looks like a new take on an old logo for a Wisconsin summer camp that had its peak years between 1955-1960 and just got bought by investors with deep pockets trying to cash in on the nostalgia.

So thinking about all the new (rumored) information over the past couple of days, is this what we're headed for:
A brighter green, but not quite the Kelly green of the 80's.
The current JETS wordmark with the 80's streaking jetstream above it, placed in an oval with black outlines?
The Jets wordmark on the chest?
I wouldn't be surprised by the jetstream logo running down the middle of the helmet, creating a white arrow/'V' towards the front of the helmet and a line down towards the back.
For the uniforms, I'm imagining a lot of black outlines or piping, with white shoulder caps/sleeves, maybe even black TV numbers, black side panels, and some cutoff striping on the pants. I even thought about 'NEW YORK' being in the Jetstream in the logo behind the Jet. and then started thinking about that running down the legs as well. Then I lied to myself and pretended Nike would never do that.
I'm still nervously anticipating some dumb, oversized military stencil numbering with black drop shadows that will make the Bucs alarm clock font look like a classic.
The unveiling will probably take place on the USS Intrepid as well.
* Everything in this post is just a ridiculous worry, but at least takes grains from the bits of rumors out there *

Isn't this the argument soccer fans in the US who defend '(City Name) FC' as a naming convention for teams? They always say the team nickname should grow organically from the fans. It seems like this is kinda exactly that.
I'm not trying to stir up anti-soccer sentiment or anything, I'm really curious - this seems to be straddling the fence and complaining about both sides.

I wonder how much cost to each club a rebrand actually costs. Does the club pick up the tab for research, designs, opinion polling, etc.? If this is strictly handled by the clubs and not MLB Properties or whatever branch would be in charge of a rebrand (actually in charge or asked by the team to take the lead)? If it's a club expense, I can imagine a supplier like Nike, Adidas, etc. offering to pay for the redesign would be a huge plus for the club.
Owners are there to make money. Clubs don't buy their stadiums, they don't pay players anymore, the have found 10-12-14 dollar beers still sell in enough volume that they can charge that price, and sell alt, one off and special jerseys and hats left and right, regardless of branding.
I mean, with all the teams chasing after a buck and not really concerned about winning or spending money without getting a big monetary return, I find it'll be rarer and rarer a club actually spends money on a redesign when some other organization looks at the tab, smiles, and says 'I've got that'.

I'm thinking fake because there's clearly not enough contrast for the Nike logo to stand out on the sleeves. It needs to at least be white, or perhaps some shade of Orgeon highlighter to be real.
Nike never misses a chance for self aggrandizing on their new designs

I'm going way back than just 'recent years', but as a kid in the early 80s, the only place I ever could see other jerseys and hats in person was the store across the street from Fenway Park. The sports store (which I think was pushed out by the team and became the team's official shop). There was very little access to other teams' highlights besides games of the week, even the USA Today didn't exist with color pictures until 1984! Sure, you could occasionally get your hands on a catalog with all the teams, sports, etc, but that seemed rare.
Then (I'm not sure which came first) but Ebbets/Mitchell Ness would start making throwbacks and old uniforms and hats (the Brooklyn Dodgers again!) Throwback games started hitting the majors, and the frequency of them increased from the late 80s into the 90s. Then Negro Leagues throwbacks started happening as well, expanding the visual landscape of the history of the games. (I know this is more baseball, but the NFL also had that one crazy throwbacks in the early 90s). The growth of cable TV and ESPN really exposed people to a lot more designs than they were previously used to seeing on a regular basis.
But I think it was a Madden game that allowed players to pick uniforms when it really hit 'mainstream'. I think with the trickling of throwback games, throwback merchandise, and the realization that people wanted to buy other team's stuff beside their local team really changed things a lot.
Once those doors of merchandising were opened, teams found a new revenue source and most leagues would start to flood the markets with throwback shirts, jackets, etc. All the while, the exposure of old logos and designs grew in the regular fan's minds, and teams continued to pocket the funds.
I think the next big leap was 'branding' as a thing. Yes, it has always existed, but it's only exponentially grown the internet, I remember one of the first times I came across Chris Creamer online was finding and forwarding a pdf of the Patriots navy Flying Elvis jerseys, and I also remember the hubbub over the Rams losing the gold stripe on their jerseys - I think a Kurt Warner figure without the stripe proved to be the leak!
So, yeah, I do think these boards, this site, Paul Lukas, all helped grow the amont of people who follow uniforms, and also exposing the general public to a wealth of information and visual reserves about them. The leagues, already acclimated with making money off jerseys, and more cognizant of branding, and the power of the viral social media landscape, bought into all of this and really push every unveiling, third/fourth /fifth jersey bigger and bigger each year, because, why not.
So in summary, exposure/throwback games, money, internet, branding, more money.
